About the Airtac MDJ Adjustable Cylinder MDJ20X15-10
The MDJ20X15-10 is an AirTAC MDJ adjustable-stroke multi-mount cylinder with a 20 mm bore and a 15 mm base stroke, extendable by a 10 mm adjustable range. Its square compact body fixes from 6 directions (front, back, left, right, top and bottom) and can be mounted side by side to save space, with magnetic-switch slots around the body. As a double acting cylinder it works at 0.15-1.0 MPa (22-145 psi) and at 0.5 MPa delivers a theoretical push force of 157.1 N, with a bumper as the cushion. No magnet is fitted on this SKU.
This is a genuine AirTAC part. The MD family is the standard multi-mount cylinder, where the rod is free to rotate unless your fixture prevents it; the MK family is the separate no-rotating version. Thread on this model is PT. We confirm exact dimensions and sizing help from the datasheet on request.

Specifications follow the official AirTAC MD/MK multi-mount data. The front cover and piston are short, so avoid an over-long stroke. An optional high-temperature seal material extends the range to 0 to 150 C. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
How to choose
Bore 20 on this double acting cylinder gives a theoretical push force of 157.1 N at 0.5 MPa, so size your load against that figure. Choose MD if rod rotation is acceptable and MK if it must be prevented; MDJ gives double acting operation with an adjustable stroke. The 15 mm base stroke sits comfortably within the bore 20 table (up to 60 mm), and the MDJ design adds a 10 mm adjustable range on top for setting the end of stroke. Because the cover is short, avoid stretching the stroke beyond the datasheet table on this compact body. This SKU has no magnet; select the S suffix if magnetic-switch detection is required. Thread is PT by default, with G available. Side-load figures come from the datasheet, so route that question to us.
Applications
Part ejection from a nest
The 15 mm base stroke plus 10 mm adjustable range suits pushing finished small parts out of a nest: the 20 mm bore delivers 157.1 N push force at 0.5 MPa, and the square body fixes from 6 directions inside a compact tooling plate.
Jig positioning with side-by-side cylinders
These compact square bodies mount side by side, so a jig can carry a row of MDJ cylinders for locating stops, each adjusted independently within the 10 mm adjustable range.
Press-fit and light staking
A short, adjustable pressing stroke fits light press-fit jobs on small assemblies: 6-way mounting lets the cylinder be fixed from any face of the fixture, and the bumper cushions the end of stroke.
FAQ
How do MDJ20X15-10 and the MK version differ?
MDJ20X15-10 is from the MD family, the standard multi-mount cylinder, so the rod can rotate unless your fixture stops it. The MKJ variant is the no-rotating version, where a fixed rod and plate prevent the rod turning. Both share the same multi-mount, 6-direction square body concept.
What can the 15 mm stroke be extended to on this model?
MDJ20X15-10 has a 15 mm base stroke and the -10 suffix adds a 10 mm adjustable range on top of it. The bore 20 stroke table on the datasheet governs the maximum; keep the combination within it, and confirm exact dimensions from the datasheet.
